@ IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 4 [,298, dated January 19, 1864 To ail whom it may concern..-

Be it. known that I, HIRAM HQSIGK, of Paris, in the county of Washington and State of Pennsylvania, have invented a new and useful Improvement in Pumps; and I do here by declare that the following is a full, clear, and exact description of the same, reference being had 'to the accompanying drawing, making a part of this specification, said'drawing being a side sectional view of a lift-pump with my invention applied to it.

This invention relates to an improved mode of operating the piston of the pump, whereby a longer stroke of the piston is obtained than by the ordinary brake or lever. and aproportionably greater quantity of water elevated within a given time and with greater facility or aless expenditure of power.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

" A'represents the body of the pump or pumpchamber,-in which the piston 1:3 is fitted. O is the nozzle through which the water'is discharged, and 1) is the check-valve at the bottom of the pumpchainher. These parts may be constructed in the usual way and therefore do not require a minute or particular description.

E is the pstonrod, the upper end of which passes through the top of the pump-chamber, and F is the brake or lower, the lllltI'dlll a, of which passes through lugs or ears bat the side of the pump-chamber. The inner end of this brake or'lever F is of semicircular form,

as shown at G, and to each end of G a cord or chain, H, is attached, said cords or chains being secured to the pistonrod E, as shown V at c c,

The semicircular end G of the brake or lever F is quite close 'to the piston-rod E, and may just touch it, the cords or chain's H fitting in grooves in the periphery of G.

From the above description it will be seen that when the brake or lever F is operated the piston B will be moved up and down, the uppercord or chain forcing the piston down and the lower one raising it up, and it will also be seen that the cords or chains will be acted uponin a line parallel with the piston-rod E, and hence much t'riction will be avoided. Besides this advantage, a longer "stroke than usual of the piston is 0btainedthatis to say, than can be obtained by the ordinary brake or levcr-and, owing to the diminution offriction, with a less expenditure of power.

Ldo not claim, broadly, the use of straps and curved surfaces for producing rectilinear motion but,

Having thus described my invention, what- 1 claim as new, and desire to secure by Letters Patent, is-

Having the end of the pump-lever made in the form of a semi-circle, G, when combined with the cords H H and piston-rod E, in the manner herein shown and described.
